TL;DR
A fair home security monitoring contract is month-to-month, requires no ETF, owns your equipment outright, and lets you cancel with 30 days' written notice. That is the SimpliSafe, Ring, Cove, and Wyze standard — and it represents the majority of the no-contract monitoring market. The red-flag contract locks you in for 36–60 months, charges 75–100% of remaining payments as an ETF, auto-renews with a 60-day notice trap, and finances equipment through a separate lender with different cancellation terms. Knowing what each clause should say lets you walk away from the unfavorable ones before you sign.
Fair language:
"This agreement is month-to-month. Either party may cancel with 30 days' written notice."
Red-flag language:
"This agreement has an initial term of 36 months (3 years) beginning on the installation date. Customer agrees to make all monthly payments for the full initial term."
What to look for: The phrases "initial term," "minimum service period," or any specific number of months. These indicate a lock-in. Month-to-month agreements will not contain them.
By brand (2026):
Fair language:
"There is no early termination fee. Service may be cancelled with 30 days' notice at any time."
Acceptable language (read carefully):
"If customer cancels prior to the end of the initial term, customer agrees to pay an amount equal to 50% of the remaining monthly monitoring fees due under this agreement."
Red-flag language:
"Upon early termination by customer, customer shall pay an amount equal to 75% of the remaining monthly payments due under this agreement."
(Standard ADT ETF formula)
"Upon early termination, customer agrees to pay 100% of the remaining monthly monitoring payments."
(Standard Vivint ETF formula)
The industry ceiling for "reasonable" is 50% of remaining payments. ADT at 75% and Vivint at 100% are above this threshold and should be treated as elevated contractual risk.

Fair language:
"After the initial term, this agreement continues on a month-to-month basis until cancelled by either party with 30 days' written notice."
Red-flag language:
"This agreement will automatically renew for successive one-year terms unless customer provides written notice of cancellation no less than 60 days prior to the end of the then-current term."
Why the 60-day notice trap matters: your renewal date is recorded in a contract you signed 36–60 months ago. Most customers do not track it, and the company is not required to send a reminder. Missing the 60-day window by even one day can lock you into another year. The fair standard is 30 days or less, or month-to-month auto-continuation with no renewal lock-in.
Several states — including California, Connecticut, New York, Illinois, and Oregon — have laws requiring companies to send renewal notices and limiting automatic renewal to consumer contracts below a certain term length. If you have already missed a renewal window, check your state's auto-renewal statute before assuming you are locked in.
Fair language:
"All equipment purchased by customer is and remains the property of customer upon payment in full."
Red-flag language (lease model):
"All equipment shall remain the property of [Security Company] and must be returned upon cancellation of service. Failure to return equipment may result in charges equal to the retail replacement cost."
Red-flag language (separate financing):
"Customer acknowledges that the equipment financing agreement with [Lender Name] is separate from this monitoring agreement. Cancellation of this agreement does not relieve customer of obligations under the equipment financing agreement."
What the separation means in practice: with Vivint, canceling monitoring does not cancel your equipment loan. You can owe nothing to Vivint for monitoring and still owe 24 months of equipment loan payments to a lender like Citizen One or Fortiva. Both obligations run concurrently and independently.
Run your contract through the Analyzer to check whether your equipment is described as owned, leased, or separately financed.
Fair language:
"Monthly monitoring fees will remain fixed for the duration of the initial term of this agreement."
Red-flag language:
"Company reserves the right to increase the monthly monitoring fee by up to 3% annually upon 30 days' written notice to customer."
The math on a 3% annual escalator on a $49.99/month base rate over 60 months:
Cumulative overpayment vs. a fixed rate over 60 months: approximately $235. That is not catastrophic, but it is money most customers do not budget for. See the full escalator analysis.
Fair language:
"In the event of monitoring center unavailability exceeding 4 hours, customer may request a prorated service credit. If monitoring services are unavailable for more than 7 consecutive days through no fault of customer, customer may terminate this agreement without early termination fee."
What most contracts actually say:
(Nothing — service levels are not mentioned)
Most residential security monitoring contracts make no service-level commitments. The company can have outages, fail to dispatch, or route calls to a backup center without triggering any cancellation rights. This is industry standard but unfavorable — knowing the contract contains no SLAs tells you something about how much the provider prioritizes accountability.
Fair language:
"Customer may cancel this agreement by providing 30 days' written notice to [Company] via email, phone, or mail. Cancellation is effective at the end of the billing period following receipt of notice."
Red-flag language:
"Cancellation requires written notice sent via certified mail to [specific address], received no less than 60 days prior to the end of the then-current term. Cancellation by phone or email is not accepted."
Requiring certified mail for cancellation is not inherently unfair, but the 60-day window combined with certified-mail-only submission creates a procedural trap. Look for contracts that accept cancellation by email — it creates a timestamp you control.
Before signing any home security contract, confirm these six things in writing — not from the sales pitch, but from the actual document:
1. Term length: How many months is the minimum service period?
2. ETF formula: What is the exact cancellation fee if you leave early, expressed as a formula?
3. Auto-renewal terms: Does it auto-renew into a new fixed term? What is the notice window?
4. Equipment ownership: Do you own the equipment, lease it, or finance it through a separate lender?
5. Price increase cap: Is there a limit on how much monitoring fees can increase per year?
6. Cancellation procedure: How do you cancel, what format is required, and what is the notice period?
